The UK and EU depend on each other in their development and economic growth. The UK is one of the main members and creators of EU. The UK has a developed economy. Moreover, UK is a sign of traditions of old Europe. If the UK stays in EU, it will have more attractive status before investors. However, it has a good reputation even without its membership in EU. So, if UK wanted to leave EU, it would have even some preferences in trade and other economic events. The reason for that is a great role of UK in the future of EU, because UK is the important player in the international scene of economics.
